To all whom it may concern:

Be it known that I, LUGIUs J. PHELPs, a citizen of the United States,and a resident of New York, in the county of New -York and Stateof NewYork, have invented certain new and useful Improvements in PolarizedRelays, of which-the following isa specification.

'My invention relates to the construction of relays ofthe class known aspolarized relays, and is designed more especially as animprovement upont-he type'of relay knownjas the Siemens polarized relay. Like thelatter,

- my relay embodies a polarized armature playing vbetween two soft-ironmagnet-cores normally polarized, so as to exhibit magnetism of the samesign, and, wound with coils of wire connected'v or applied in such waythatthe current which increases the strength of onepole will 'decreaseorreverse Vthe polarity of the` other; but in the manner of charging theelec-.

'tro-magnets and in the-formand mounting,

' Sto., of the armature, andthe construction l and arrangement ofthevarious parts,' it em bodies improvements which, among other things,tion, as well-as to the 'stabilityof adjustment. In my improved' relaythe electro-magnets are charged, not fromtlie same pole of` thepermanent magnet, but from separate poles of 3o a multipolarmagnethaving acommon oneentral pole by which the armature' is'charged orma Iletized. I

he armature off position vdirectlynpon ,themass of iron formingitscharging-pole, and preferably provided with knife-edge bearings.

The improved details an stitnting my inventioniwill be" moe specific- 40ally hereinafter 'set out in connection with the accompanying drawings,and will; .thenlbe specified in the claims;

'I heelectro-magnets B-B'are charged by magnetic contact or contiguity withseparate magnet-poles, which poles are preferably the poles of amultipolar magnet, having va common or central pole of .one sign andseparateor distinct poles of the opposite sign. Such rnultipolar4 magnetAmay be of steel and have permanentvv magnetism of its own, or it', inay be kept 'constantly charged by electricity. It may be made in asinglepiece, or it may be compound, or made up of several magnets hav-ving like poles conjoined to forma common or central pole.
